St. Helena
Likely named for nearby Mount St. Helena, in the North Bay region of the Bay Area. Ag, trailer and heavy equipment repairs done in the field.

Angwin is a census-designated place in Napa County, part of the northern San Francisco Bay Area, located within the Howell Mountain AVA at an elevation of 1,749 feet. It is named for Edwin Angwin, a native of St. Agnes, Cornwall, who in 1875 bought a 200-acre parcel within the Rancho La Jota on Howell Mountain and established the Angwin Resort. The rig crosses the valley from the foothills for repairs and fabrication at ranches, vineyards, homes and jobsites across Angwin.

Before 1875, Rancho La Jota was held in its entirety by William Campbell Watson, whose wife Elizabeth Anne Davis was the granddaughter of George C. Yount. Watson began to sell off portions of the rancho in 1875, Edwin Angwin's among the first parcels, and a community soon grew up around the success of the Angwin Resort. By the 1900s, Edwin Angwin owned almost 1,600 acres in the area. Vineyard trailers, ranch implements and truck hitches get repaired right where they sit, because the rig carries engine-drive welding power, wire feeders, an oxy-acetylene torch and a plasma cutter.
For directions, give the road and the nearest cross street, and a photo of the spot helps on the mountain.
Yes. Angwin had 2,633 residents at the 2020 census across 4.9 square miles, and it first appeared as a census-designated place in the 1980 census. Highway 29 brings the rig to St. Helena, and the drive climbs Howell Mountain from there. Call or text and we'll set a time.
Yes. A cracked log splitter beam, a bent brush cutter deck, a broken stake bed rail and a split trailer tongue get welded right on the property. Send a photo and the road and we'll plan the trip.
